Looks like thumbnail image server has crashed again

I can't swear to it, but it seems like this happens on or near the weekend towards the latter part of the month?
The thumbnails for user avatars on my homepage have stopped loading, which indicates to me that other images (mainly thumb previews) will stop loading soon.

That is happening every week and now the gifs doesn't work anymore... the servers are overload or the system is fading bit by bit
